To all whom it may concern:

Be it known that 1, ANDREW J. BRADLEY, a citizen of the United States, and a resident of the city of New York, county of New York, and State of New York, have invented a new and useful Improvement in Machines for Oiling Paper, of which the following is a specification.

My invention relates to the oiling of paper and has for its principal objects to expedite the work of oiling paper; to secure uniformity in the product, to avoid waste and otherwise to economize labor and material.

It consists in the parts and in the arrangements and combinations of parts hereinafter described and claimed.

in the accompanying drawing which forms part of this specification and wherein like symbols refer to like parts wherever they occur, Figure 1 is a front elevation of a machine embodying my invention with a part of the oil tank broken away Fig. 2 is an end elevation thereof, and, Fig. 3 is a vertical cross section on the line 33 of Fig. 1; Fig. 4 is a vertical cross section on the line 4-4. of Fig. 5 showing the upper portion of the mechanism; Fig. 5 is a detail view of the power transmission train and, Fig. 6 is a detail elevation illustrating the means for adjusting the finishing rolls.

The main frame of my machine comprises end frames 1 secured by rods 2 or other suitable means. In the upper portion of the frame is a shelf or table 3 upon which rests an oil tank 4:. Journaled in the framework sists of two members, the upper one 11 of which has a looped portion adapted at one end to hook over the shaft of the roll 6 and having its opposite end provided with a j laterally arranged eye. The other member 12 has a loop at one end adapted to hook l under the lever arm and its free end is screw- 1 threaded and extended through the eye in j said first mentioned member. A helical i spring 13 surrounds said threaded end and bears against the eye portion of the first men works on the threaded end of said last mentioned member. By varying the position of the nut, the spring is more or less compressed and the pressure of the roll 8 against the roll 6 may be adjusted at pleasure.

Both the upper and lower feed rolls have circumferential grooves 14 therein adapted to accommodate the guides for the paper without interfering with the rolls. The lower guides 15 are a series of rods which are hooked over the upper front edge of the tank and thence inclined downwardly between the feed rolls and thence upwardly beyond the rear side of the oil tank close to the meeting tioned and thence are doubled back and looped over said rear edge of the oil tank. The upper guide comprisesa series of curved rods 16 which are mounted on a rock shaft 17 at the rear of the feed roll 6. These rods curve downwardly under the upper feed roll and extend through the circumferential l groove therein and terminate in an upturned above this oil tank is a shaft 5 adapted to be portion. From the rock shaft the rods driven from any suitable source of power, curve upwardly and have a fender plate or and upon said shaft is mounted a wooden l guard 18 mounted thereon above themain roll 6. The oil tank a is provided with an feed roll 6. Extending laterally through the overflow pipe 7 and the roll 6 is made short rock shaft is an arm 19 whose end is conenough and of proper diameter to extend nected by a tension spring 20 to a portion of into the tank some distance below the top of the framework, whereby the spring tends to said overflow pipe. Inside of said oil tank hold the upper guide rods upwardly against and beneath the feed roll 6 is a second wooden the under side of the main feed roll. When roll 8 from whose ends projects a shaft 9. it is desired to lower the fender-plate or The ends of the projecting shaft are jourguard, it is only necessary to press downnaled in the ends of the lever arms 10 prowardly thereon.

vided therefor at the ends of the tank. Journaled in the rear portion of the frame- These lever arms are bent upwardly to clear work are a pair of finishing rolls 21, 22 the side of the oil tank and thence downwhich are preferably made of steel covered wardly, their ends being pivotally mounted with a coating of some composition that is on the framework at substantially the same not deleteriously affected by oil. In order to elevation as the axis of the roll 8. The roll l j provide for the adjustment of the finishing 8 is held upwardly against the main feed roll 1 rolls relative toeach other, one of said rolls 6 by means of a tension l1nk. In the con- 22 is journaled 1n a journal box 23 which is struction illustrated, the tension link conslidably mounted 1n the main frame. Adjustpoint of the finishing rolls hereinafter mentioned member and against a nut which yoke 38 which straddles the belt.

be so designed that the finishing rolls and the be varied by varying ing screws 24, 25 extending through holes I provided therefor in the main frame on oppo- I site sides of said bearing box constitute a convenient means for accurately adjusting the 1 position of said roll 22. I Mounted on a suitable platform or table provided therefor in the lower portion of the main frame is a large drip tank 26 of sufficient size to catch any oil that may drip from the paper sheets or the rolls. flow pipe from the oil tank opens into this i drip tank. Located in the lower portion of f the framework is a pump 27' whose suction pipe 28 opens into the drip tank near the bottom thereof, preferably without perforating said tank. The delivery pipe 29 of said pump in like manner opens into the oil tank in the upper portion of said framework.

The moving parts of the machine may be actuated from any suitable source of energy. In the construction shown in the drawings, a belt 30 is arranged to fit over a fixed pulley 31 on the main driving shaft 32 of the ma chine, which is provided with. an idle pulley 33 and any suitable means for shifting the belt from one pulley to the other. In the construction shown the belt shifter cornprises a transversely arranged rock shaft 34 whose ends are provided with handles 35 for manipulating the same, which handles are located in position for convenient manipulation by the operator either at the front or at the rear of said machine. An arm 36 of the rock shaft is connected by a link 37 to the By this arrangement the turning of the rock shaft causes the belt to shift from one pulley to the other. Upon the driving shaft is a sprocket wheel 39 which engages a sprocket chain 40 which in turn engages a sprocket wheel 41 provided therefor on the shaft of the main feed roll 6. On account of the pressure of the secondary feed roll against the main feed roll, the secondary feed roll is actuated thereby.

Mounted upon the main shaft is a gear or pinion 42 which meshes with a gear wheel 43 provided therefor on one of the finishing rolls 22, and this last named gear 43 in turn meshes with a like gear 44 on the other finishing roll 21 of the pair. The gearing should The overfeed rolls should have the same circumferential velocity.

The pump ispreferably actuated by means of a belt 45 which passes over pulleys 46, 47 provided therefor upon the driving shaft and the pump shaft, respectively.

In operation, a large volume of oil is placed in the drip tank and the oil tank is filled with oil to a predetermined level, which level may the elevation of the up per end of the overflow pipe. The operator at the front of the machine then feeds the sheets of-paper or paper heard one by one by advancing the edge of the sheet downwardly along'the lower guides until the front edge of the sheet is gripped by the feed rolls. In this forward movement, the sheet passes between the upper and the lower guides and is moved forwardlyby the feed rolls. The respective guides act as strippers to prevent the paper from adhering to either of the rolls, and guide the paper directly into the finishing rolls. In the first portion of this operation, the paper is entirely submerged in the oil, while in the latter part of the operation, the finishing rolls squeeze out all surplus oil and secure a thorough and uniform distribution of the oil throughout the paper. In case it is desired to repeat the fmishing operation alone, the fender or guard plate is depressed and the sheets are fed over it into the finishing rolls. By these operations, great rapidity of operation and uniformity of product can be attained, and the process avoids most of the waste heretofore incidental to the manufacture of oiled paper board.

Obviously, my device is capable of considerable modification within the scope of my invention, an d therefore I do not wish to be limited to the specific construction shown and described.
